5. Smart growth is an urban planning and transportation
theory that concentrates growth in compact walkable urban
centers to avoid sprawl. It also advocates compact, transit-
oriented, walkable, bicycle-friendly land use, including
neighborhood schools, complete streets, and mixed-use
development with a range of housing choices.

Roof Runoff
1. RAIN GARDEN
Roof runoff is directed into rain gardens located
at either end of the plaza. Storm water will be
detained, filtered and infiltrated back into the
soil. Any water that does not infiltrate will be
slowly released into the Bio-infiltration planter.
2. BIO-INFILTRATION PLANTER
Surface run-off and run-off released from the
rain garden is directed into a central bio-infil-
tration planter. This is planted with native veg-
etation that will help filter out particulates and
pollutants from the water as it moves towards
the inlet. Any water that does not infiltrate back
into the soil will be slowly released into an un-
derground detention system.
3. INFILTRATION BED
A centrally located gathering space will
be comprised of a variety of pervious
pavements (gravel, wood deck and
grass) above a structural soil infiltration
bed. This will reduce the amount of im-
pervious surface on site by approximate
30% and will allow surface runoff to infil-
trate on-site without entering a structured
system.
4. DETENTION SYSTEM
An underground detention system will be
located within the infiltration bed. Any
runoff that does not infiltrate back into
the soil will be detained in this system
and slowly released into the city’s sewer
system.
5. DISCHARGE
Any runoff that remains after circulating
through this series of Best Management
Practices interventions will be released into
the city sewer system at an appropriate rate.

Environmental Benefits
• Capture rainwater before it reaches the ground
• Store over 100 gallons of rainwater, reducing stormwater runoff.
• Improve air quality, producing oxygen and sequestering carbon
• Block up to 90% of the sun’s energy from reaching the ground
Economic Benefits
• Home values near mature street trees are higher than those in areas where there are none
• New York City’s recent tree expansion campaign esSmates that there is a $5.60 return for
every dollar spent on tree planSng and care
• Promote socializing and gathering
